SOURCE: coolant in # 1 cylnder\clean intake port of intake manifold

Check the lower intake gasket again the new gaskets that are being use made out of plastic with rubber port seals sometimes don't seal right I still used gasket sealer with the new plastic gasket even if it has rubber seals. MY 4.2 v6 had that problem but I went ahead and replaced the head gaskets also just to cover all the bases. And my F-150 has 210,000 miles on it. Make sure you tight the bolts I know it probably calls for something like 8 ft lbs which to me is not tight enough. Double it.

SOURCE: 98 Expedition coolant leak top back of engin

Sorry im late with this,i couldnt seem to log on....The answer to your question is YES,there is a steel line under the intake with a short piece of rubber line attached to it and you can just about see it from the front of the intake with a light,it can leak and cause coolant to run off the back of the engine,The intake gasket set alone is about $40.00 and i dont know about the rubber line,i have seen it physically but havent changed one yet.Note the date of manufactor just incase,i bought an intake set for a 99 and the engine design was changed half way through...its not too hard to pull off the intake and re-install,you will need a 7mm socket for the coil packs,8mm socket for the fuel rail bolts and lower intake bolts and power steering bracket bolts and throttle bracket bolts,10mm socket for the intake bolts and alternator bolts and egr valve,and a large cresant wrench for the exhaust tube thats connected to the egr valve,flat screw driver for the air cleaner...and plenty of extensions with a swivel to be able to get to the back bolts of the intake....just incase you do it yourself this info could make it easier to gather tools.Its about a 3 1\2 to 4 hour job start to finish for the first time doing it,includes cleaning everything..Good luck

SOURCE: My Explorer has the same coolant leak

Check closely where is it leaking from. If its coming out between the engine block and the cylinder head, very urgent depending how much is leaking, other like radiator or water pump can be temporary fix with sealer you buy at auto parts store although one has to monitor their engine temperature moore closely. Keep in mind any water leaks will cause nothing but overheat the engine. Water flow through out entire engine and cool the most important parts, the cylinder head where most heat created and need to be cool, if not the head can warp cause the head not to seat properly to the engine block, reaction would cause poor compression, rough idles, poor gas mileage, poor performance and ect. You can still drive the vehicle as long you pay attention to the temperature guage and the smell of the engine. You can smell if the engine is running hot, so just keep extra water container with you just incase you run low on fluid. Try not to run straight water in the systems, water reach it boiling point quicker than antifreeze.

SOURCE: fuel leak under turbo on 1997 ford 7.3

Is the fuel in the valley right under the fuel pump? If so, your fuel pump might have failed and is leaking out of the weep hole.

Other places to look would be the fuel filter seal and a bad o-ring in the fuel drain relief valve.

Good luck

My 2008 Chevy uplander engine light on and the code shows for cam shaft sensor and intake manifold what I do


The intake code means its leaking from the intake,bad gaskets, or a vacuum leak. check for bad gaskets on intake manifold. You can tell by putting a bit of oil around the maifold. if it is leaking the engine will flair up. To check this, External leak-- Coolant seeps through the broken intake manifold gasket to the outside of the engine. If its bad enough you will see coolant dripping from gasket. Coolant seeps through the damaged gasket to the inside of the engine, mixing with motor oil. If you suspect an internal leak, check your oil dipstick. Or if you have a substance under oil filler cap that looks like a milkshake, Oil is mixing with coolant. this means intake gaskets are bad, Now for the camshaft sensor, If you have a manifold leak. this could be giving you a false camshaft reading! Because, If sensor is bad vehicle will not start unless theres a wire problem. Symtoms of a bad sensor are--- engine sputtering, poor acceleration, stalling/inability to start. HopeI helped you out! Good-Day!

Tip

Intake Manifold gasket replacement and/or leaking= Ford


Intake Manifold gasket~

Replacing intake manifold gasket:
Replacing the intake manifold gasket, I used the tube kind, it's a make it youself for about $6 (it's blue and the consistancy of toothpaste) follow directions carefully! You can get a tube at Autozone or any car parts store. Has been working great. Just ask the cashier for the make it yourself kind of intake manifold gasket. Sorry, I don't remember the name of it, it's been that long...lol...

As for the Intake Manifold leaking coolant....It could, but shouldn't. One of the largest problems I've seen for coolant to leak out the Intake Manifold has been due to pressure in the system somewhere... Check the classic area:
Water pump- look for either water seapage and/or coolant. You'll know if it is because you will see real water either coming out of the water pump leak hole or under the thermostat. Most of the time coolant will pool where your heater hose runs in the intake manifold.

Mentioning heater hose. Check for leaks, holes, and/or cracked heater hoses. In-addition to the water pump, heater hoses...Check the transmission system, exhaust system, fuel system, radiator system, A/C system, secondary fan (located above the water pump housing), and thermostat.Also, check all electrical connections....Hummm....This is almost the entire workings of the vehicle.

NOTE: "It seems to be an infinity kinda thing... Once one thing starts to fail and is ignored, you are bound to be fixing a chain of event failures. Therefore, Do not ignore even the smallest problem or you'll be bound for life in repairs...."

Coolant line under intake is leaking 95 town car


95 Lincoln town car coolant leak under intake SOLUTION EASY

Ok this is a 4" piece of hose leaking on a tube that runs under the intake manifold and fastens to the rear of the engine with 2 small bolts that are very hard to get to. The heater core hooks up to this tube with a 5/8 hose that's 3/4 on the other end going into the heatrer core.
Solution:
remove alternator
see clamp on hose?
remove it.
If you can't remove it, clamp vice grips on it and take a steak knife and cut through the hose towards the rear of the engine. Now with large screw driver pry the hose and clamp off the nub on the rear of the water pump housing. You may have to move the tube and remaining hose out of the way first. Just stick your hands in there and force it out of the way. Now you have a clean nub to hook a 5/8 bypass hose to. Here's where you get it. Go back to the heater core and and remove the hose that connects to this tube that runs under the intake. Just cut it where it hooks to the tube and remove it carefully from the heater core because this is now your needed bypass hose. Now with a couple feet of 3/4 hose and a coupler you have all you need to reroute this water outlet around the engine to the heater core. Take your hose you cut from the other end of the tube and removed from the heater core and and fasten it to the nub on water pump housing use new screw type stainless Steel clamps. You have to take this one apart to put it on. Stick a 3/4 coupler into the other end and route a long section of 3/4 hose under alternator to the heater core using SS clamps where needed. job done... Just leave the old tube where it is under the intake manifold......Thank you Very Much

My 2006 pontiacgrand prix is leaking coolant right above the water pump. There is an L shaped pipe that seems to be where the leak is coming from. Does anyone know what this piece is and how hard it is to...


This was a common issue with these engines. Unfortunately there is no easy way to fix this problem other than to remove the intake manifold and replace this plastic tube along with the intake manifold gasket itself, these engines were common for the intake manifold gaskets leaking and also for that tube to crack over time and start to leak as well.

Like i stated, unfortunately there is no real "easy" fix for your problem. I have replaced many of these tubes and many intake manifold gaskets on these engines. I would not recommend doing it yourself unless you are familiar with these engine, there are special torque specifications for all the bolts. I do know that the intake manifold repair job usually runs somewhere in the ballpark of $800 - $1000 or more depending on where you take it.

Hope this helps...

Heating and cooling system leak under intake manifold. I cannot see the heater hoses without removing the intake manifold. What should I be looking for, this is a major leak.Thanks, Eric


You are not going to know for sure until you pull the manifold, but should be a easy fix, will be either the round welsh plugs, a corroded steel tube , or hose and clamp.
With the manifold off, a pressure test will squirt the coolant out , if it isnt immediately obvious where the leak is

Coolant leak at intake 1994 Buick LeSabre 3.8 ltr


There are several areas of possible leakage. One is the hose and plastic outlet from the intake manifold on the passenger side of the engine. The hose runs low, underneath the alternator. The plastic outlet cracks, the hose gets old, the clamps on the hose can also be loose. The replacement outlet from the dealer is steel, not plastic.
Another possibility for leakage is on the driver's side of the intake manifold. Underneath the air inlet is a metal cover on the end of the intake manifold. This covers the coolant passages at the end of the intake. Mine was oozing antifreeze..you don't have to pull the intake to replace this.
The other place for leaks is the intake itself..requiring removal of the intake. I've done this...I don't think it is that bad of a job. However, if you put in a new intake, don't forget to put in a pcv valve..it fits under a small cover at the right rear of the intake manifold.

If it is not necessary to replace the coolant tube in the intake manifold if it is leaking antifreeze, how do you fix the leak even if you do flush out the system and put green antifreeze in? I am also...


I'm assuming you are talking about the 3800 v6 engine?
I don't know what hose or tube you are talking about either. There is not any coolant going through a hose in the intake manifold. There are two bypass coolant elbos on the passenger side of the engine going into the intake and timing cover from the intake and the heater core. Is this what you are talking about.
And NO green coolant in a 97 Dexcool only!

1995 Taurus leak around under intake manifold

Coolant leak


This engine has a plastic intake, jsut inside of the throttle body is a tube that comes from the EGR. It will burn through the plastic into a coolant passage located inside of the intake. You will need to replace the intake manifold and if you want there is a revised lower intake manifold with a slightly smaller diameter tube to prevent future burn through that will prevent a reoccurance. However, it is a costly repair for what is a infrequent failure. I suggest just replacing the upper intake manifold. They are now available through the aftermarket.
